A communication channel with AWGN operating at a signal to noise ratio SNR >> 1 and bandwidth B has capacity C1. If the SNR is doubled keeping B constant, the resulting capacity C2 is given by-A-C2 ≈ 2C1B-C2 ≈ C1 + BC-C2 ≈ C1 + 2BD-C2 ≈ C1 + 0.3B-B-C2 ≈ C1 + B

Question

A communication channel with AWGN operating at a signal to noise ratio SNR &gt;&gt; 1 and bandwidth B has capacity C1. If the SNR is doubled keeping B constant, the resulting capacity C2 is given by-A-C2 &asymp; 2C1B-C2 &asymp; C1 + BC-C2 &asymp; C1 + 2BD-C2 &asymp; C1 + 0.3B-B-C2 &asymp; C1 + B

APTITUDE CRACK · Accepted Answer

B C2 &asymp; C1 + B C = B log2[1 + SNR] C = B log2[SNR] C&#39; = B log2[2SNR] = B log2 SNR + B log22 C&#39; = C1 + B.
